    I hope you are starting to mend by now. Your jaw should mend well if they used surgical plates to fixate the fracture. You might also have cracked some molar teeth internally, which may not show up for some time afterwards. Symptoms: sensitive to cold and chewing fibrous foods.
    I had a similar crash on my DRZ when I got a screw through my knobby tyre at speed. The sudden loss of pressure made the back end swap form side to side violently. I managed to hang on from 60 mph to stationery and then topple over. Scared the crap out of me though.

    Thank you. I have recovered surprisingly well considering the shape I was in and now have 2 lighter Hondas to keep me in the saddle. I did in fact crack a molar but not too badly and had that repaired a while after my jaw healed. The shoulder was the worst of it. The doctors in Fairbanks didn’t think they could do anything with it, but I found a good shoulder specialist in CA that put a Ti rod in and pieced it back together. Then I put in a year of physical therapy to try to get back in shape.

    So the part BMW call the inner socket, which is an aluminum spacer between the sprocket bearing and the rear, right side axle bearing, has a lot of play in it, but looks normal. Should this part rattle around when installed?

    Mine was always loose until the wheel was installed. Then it would be tight as the axle was torqued.

    Having a bearing driver makes the job a lot easier

    The F800GS really does love to eat bearings, doesn't it? 31,000 miles on mine and I've gone through two sets of rear bearings (just installed the 3rd), a set of front bearings, one set of steering head bearings...

    Never had any other bike go through them like that!

    Has anyone found after market seals cheaper than the Bimmer ones? I just priced new rubber for the front and rear and they are coming in at just under $100.

    Any bearing shop should have seals
    On the 800:
    3- 30x47x7
    1- 25x47x7

    Wow I just had a rear bearing failure this past weekend riding home from Big Sur California!
    I heard the same tick tick tick and had a slight wobble below 30mph.
    I inspected the bike and saw nothing out of the ordinary. Thinking it was a tape weight came Loose. Well coming home riding at 50 mph just cruising I felt hesitant on left turns. When we stopped I let my friends know how apprehensive of riding. Especially doing left sweep turns.
    We kept on came to a view point and inspected the bike and I found aluminum shaving on the rotor side (left) of the bike. We moved the rear tire side too side and finally saw that the rear bearing blew out. I think I have done some bad damage to the hub and the rear brake caliper.
    I was lucky we weren’t on a 80 mph pace. Or things would of been not so good. Time too tear down this rear tire and get to work.
    Here some pics!
    I feel lucky! I didn’t crash like I have read hear!
    Gotta say this is not a good feeling seeing that this is a constant problem!

    Glad to see you made it out ok that situation in one piece. That could have been bad.

    Appreciate a little help to a Noob inmate.

    I read every post of every page of this thread and the related threads as my wife has a suspected bad hub (bearings lasted 6,000 miles).

    I had a post from Woody saved that pretty much had everything on one post that a bike shop would need to repair her hub.
    the hub specs including the crush, the bearings and high speed water proof bearing grease, etc...

    It had rx= somewhere in the text, and Woody has more than 1 of those. A forced computer reboot wiped it out and I've searched for it and can't find it.
    I'm now re-reading posts looking for it.
    If you know what I'm talking about or can find it as I'm not having any luck that would be great.

    or this one...

    http://advrider.com/index.php?threads/wheel-bearing-disintegrates-f800.499504/page-69#post-19074691

    I use the following google search when trying to find obscure references, as long as you can remember a key word or two.

    search terms site:advrider.com inurl:"499504"

    where the inurl # is the thread #, can be seen in the address bar of your browser, right after the thread title. Search terms are what ever (hopefully) unique search terms you are looking for. In your example I used:

    woody rx= site:advrider.com inurl:"499504"

    hope this helps

    Taking my wife's wheel to a local bike shop that says they can measure and hone the hub if needed.
    I bought bearings and filled them with green grease (boat trailer bearing grease).

    I have about 5 pages of notes in a word document for the bike shop in case they need it.

    Wish me luck!

    My rear brake side wheel bearing just disintegrated and I'm now stranded in Burns Lake BC en route to Alaska

    Alaska Canada shared ride report post link:
    https://advrider.com/index.php?thre...he-road-updates.1298397/page-20#post-35376434

    I suspected a wobble about 100kms before and inspected the rear wheel and axle nut/position as the chain had just been replaced by a mechanic 228kms before. I watched the 2 mechanics swap the chain and none of us suspected anything at that point (unfortunately we didn't remove the rear wheel to inspect the bearings, it was Saturday afternoon of a long weekend)

    Rear hub, brake, spacer etc damaged. I think I may have to tow the bike back to Prince George and fly out

    What year of bike do you have?

    This is scary to me, considering that the bearing wasn't obviously starting to go, it just goes... that's borderline justification for a class-action lawsuit against BMW.

    Get on the web and buy a used rear wheel.
    Fastest way to get back on the road.

    2014 with about 22k kms. First 10k or more was strictly street and since last summer 50/50 off road. All bearings were inspected before this trip at about 15k kms

    I also had a 2012 that I rode all over Europe and Canada without issue. Rear bearings got a bit crunchy at 42k kms so there were replaced in June 2017 (after over 5 years)

    Hey Jack. Forgot to say in my first response that I feel for you. Had the final drive crap out on my 1150 GS in Saskatchewan. Nearest dealer a day away. Hope you aren’t on a tight deadline. Used rear wheel should be 500 CDN. Good luck.

    Welp, I'm changing the bearings ASAP in that case - I have a 2014 w/ about 40K on it. I check the lateral play pretty much everytime I check my tire pressure and it's solid so far, but that's no indication that I'm safe.

    Now to find out what kit I need to buy.

    All 5 bearings are 6204. Get a bearing puller, heat gun, cheap IR thermometer. Doing all 5 takes an hour once the wheels are off. New seals as well. Don’t buy at BMW hit your local bearing supply. Check the aluminium spacers as well. If you do a lot of dirt they wear and then the seal lips having nothing to rest against. The early 800s had manufacturing issues for sure. I have seen the bearings go on a lot of bikes of all brands though. Dirt, pressure washing all contribute. I check mine by feel every time the wheel is off. If they feel even slightly wonky it is time to change.
